To all whom it. may concern: v Be it known that I, lVAi/ricn L. FonwAn'D, a citizen of the United States, residing at wWest Berkeley, in tl'1e'ctmnty ot Alameda and. State `of California, have invented new and usefnl Improvements in lligh-Pressi-lre Turbine Pumps, of which the f ollpnving is a' specification.

la method of securing the guide Yanes placed in the throat surrounding the ruimer in s. rotary oi" turbine pump, and. to so forni the said guide vanos that they may be securely fixed in place, conveniently finished, and separa-bly removed incase of renewal or repair. f vMy intention consists of the parts and the'-eonstruetionand combination of parts as hereinafter more fully described and claimed, having reference to theae'companying. drawings, in which- "Fifgure Iis a vertical,longitudinal section ofa three stage eentrifug'ga l pump'. Fig. 2 is'a detail View' of `mide ."anes and runner.

Fig. 3 is a detail View of the-guide Yanes.Hl

Fig. 4 is a-sect'io'n of Samebn linea-'a of Fig. 3. Fig. :Tis adetail View of modifical,tion of guide vane. Fig. G 'is a section on l'i'i'ei-) of Fig.

ln a turbine pump with ,n`ti( le vanos, it has been found in practice that ther-reis an intense vibration ot' the Huid issuing from -the rim of the runner due to the'fluid beingr divided by the alims or blades of the runner, and that it is necessary to secure the guide vanos surrounding the runner rigidly, to pi-'esent the said guide Yanes 'from having;l thev slightest vibration-'which would cause excessive wear and breakage. A further object isto so construct the guide vanos of a turbine pump that they.

may be separably and perfectly machined and in ease of breakage of one or more of 'the said guide vanes they may be renewed without the loss of the whole set.

{eferring now lmore specifically to the drawings, Fig. l shows a vertical longitudinal 4snction .of an ordinary form of a 3- st'ag'e turbine pln-np, show1ng the runners mounted ona single shaft, the said runners located in separate ehan'lbers, and lluid passages leading from the annular openings or `tln'onitslw- "L -fl sui'rou-nding the runners AQ-Qw---Zl to the succeeding r1.im'1crs, and [inally discharging into the d'iseha'rge shell HIGH-PRESSURE TURBINE-PUMP.

. My inyention relates more particularly to It will ybe observed that the said anni'rlarA openings or thro-.lts l--l--l" are fornu-ld-be' 1.-; tween the side walls 44 of the sulri/oinedl shells 5-5 -5", and covers (5 63 and that eonnterbores or grooves are formed-in the said side walls 4 4' near the smaller diameter, which receive the outwardly pre= Jeetingsecuring segments 4(--G wliiellar east ilfitegral with, and are partof the guide Yanes 7-Z-7 b.

Thecombination in a turbine. pump havmga sha tt and runner carried tl'lereon, a' housing and an annular openingr extern-n' to the runner, ot.i indepemlent guide vanos forming fluid passages, said vanes'each havingr projecting segments, means to' removahl y seeure said van-es in the al'l'nular opening, and counterbored channels with which the vane segments engage.

3. The combination in a turbine pump having a shaft and ruimer 'carried thereon, va" housing and an annular opening exterior to the ruimer, said opening lhaving counterbores in the sides, of guide vanes located in the annular 'opening and having outwardly projecting segments fitting into the coun# terbores, and means to independently secure the segments in the annularopening.

rior to the runner, of independent guide vanos located inf'saidehannel, one o1` more .segmentsV projecting from each vane, and

countcrbored ,channels with which the vane 3o segments engage.

6. The combination in-a turbine pump having a shaftand a runner carried thereby, ahous'ing and an annular channel exterior to therunner, of independent guidevanes located insaid channel, one or more segments projecting from each vane, coun terbored channels'with which the vane segments engage, and bolts by which each Vane is imlcpondently and removably secured.

7. The combination in a turbine pump having a shaft, Aand a runner carried thereby, a housing and an annular channel exterior to the runner, of independent guide vanes located in said channeLone or more segments projecting from each vane, counterbored channels with which the vane segments engage,and securing bolts passing through the shells, and the body of each guide vane.

8. A rotary pump consisting of a shell or casing inclosing an interior chamber, 'a runner or impeller of smaller. diameter than the chamber, and revolublc therein, independent vanes located in the chamber cxterior to the runner, each having transversely projecting segments and corresponding annular channels in the easing walls into Which the Vane segments eiitend 9. A rotary pump including'a shell or casing, a runner revoluble Within the Shell, independent tangential vanes vsurrounding the runner and having segments projecting from the sides, annular channels in lthe cas'- ing Walls into which the segments extend, and bolts passing throughthe solid portions of thel vanes and the casing.

l0 Tedgeshaped curved guideJ vane for4 turbine pumps, having one or more securing segments extending from the sides of the vane, said vane having aboltfhole through its solid portion.
